v2026.6.23

Rules Modularization

• Modular rules architecture: Split the monolithic GEMINI.md rules file into 6 focused, single-responsibility files: core-protocol.md, request-routing.md, universal-rules.md, code-rules.md, design-rules.md, and quick-reference.md. Enables conditional loading.

Removed

• GEMINI.md: Replaced by the 6 modular rule files above.
